Sigma Announces New 18-200mm F3.5 - 6.3 DC OS (Optical Stabilizer) Lens

The Sigma Corporation is please to announce the new 18-200mm F3.5-6.3 DC OS lens. This high zoom ratio lens is exclusively designed for digital SLR cameras and is capable of covering a wide range of focal lengths from wide angle to telephoto.

• Equipped with Sigma’s own OS (Optical Stabiliser) function
• Two SLD (Special Low Dispersion) glass elements and two aspherical lenses
• Exclusively designed for use with digital Single Lens Reflex (SLR) cameras

Optical Stabilizer
It is equipped with Sigma’s own unique OS (Optical Stabilizer) function. This function uses two sensors inside the lens to detect vertical and horizontal movement of the camera and works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. It automatically detects movement of the camera and compensates for camera shake when shooting moving subject such as motor sports.

Reduced Flare, Ghosting, and Lens Aberrations
Two SLD(Special Low Dispersion)glass elements and two aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer lens coating reduces flare and ghosting. This lens provides superior image quality throughout the entire zoom range.

Inner Focusing System
An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using circular polarising filters and the petal-type lens hood supplied.
